Probe on radiation leak at Indian nuclear plant

New Delhi: An official says authorities are investigating the radioactive contamination of a water cooler at a nuclear power plant in southern India.

According to a statement released by the plant, workers at the Kaiga nuclear power plant, about 280 miles (450 kilometers) northwest of the southern city of Bangalore, tested positive for tritium contamination after drinking from a water cooler at the plant.

In Sunday's statement, managing director S.K. Jain said the contamination was a cause for concern and the leak may have been intentional.

The statement said the leak was detected on Wednesday but did not say how many workers had tested positive. Local news reports said 55 workers were affected.

The statement added that no one needed to be hospitalized and the incident did not affect public safety.
